Lexus vehicles are built on Toyota's proven engineering — which means NGK is the OEM plug supplier for virtually every Lexus model. Here's what to use to maintain your Lexus's refined performance.
Lexus IS, ES, and GS (4-cylinder and V6)
NGK Laser Iridium plugs are OEM spec for most Lexus 4-cylinder and V6 engines. The 2.0L, 2.5L, and 3.5L V6 engines in IS300, ES350, and GS models all use NGK laser iridium as the factory fitment.
Lexus LS and GX (V8)
The 5.0L and 4.6L V8 engines in LS and GX models also use NGK OEM spec laser iridium plugs. These engines have 8 plugs and benefit from changing all at once to maintain smooth, consistent power delivery.
Hybrid Lexus Models (ES 300h, RX 450h)
Hybrid Lexus vehicles use Atkinson-cycle engines that have specific thermal requirements. NGK Laser Iridium OEM spec plugs are essential for hybrid applications — the engine operates in unusual patterns and plug quality matters more, not less.
Service Interval
Most Lexus models specify 60,000-mile iridium plug replacement intervals. However, the hybrid models may specify 120,000 miles — check your owner's manual for the specific interval.
